New political throwdown: Meghan McCain vs. Bristol Palin

It's on like Donkey Kong:

In her memoir due out Friday, "Not Afraid of Life: My Journey So Far," the 20-year-old daughter of former Alaska governor/potential presidential candidate Sarah Palin reveals her true feelings about the father of her son, the daughter of her mother's 2008 running mate, and much more.

Palin writes that the first time she met the 26-year-old daughter of Sen. John McCain, she "ignored us during the entire visit." This was just before Senator McCain introduced Sarah Palin as his running mate. Palin adds that she "had a sneaking suspicion I might need to watch my back."

"Every time we saw Meghan, she seemed to be constantly checking us out, comparing my family to hers and complaining," she writes. "Oh the complaining."

Palin seemed to have better first impressions about John McCain's wife, Cindy, still picked up on a subtle creeper vibe:

"I'd never seen people with so much Louis Vuitton luggage, so many cell phones, and so many constant helpers to do hair and makeup," Palin writes, adding that the would-be first lady looked "like a queen" and held "herself like royalty."

Palin writes that she was shocked when the senator's wife offered to be a godmother to her unborn baby: "I had just met her and I wondered why she wanted any type of guardianship over my child."
